Description of key information

EC50 (48 h): 284 mg/L based on immobilisation of Daphnia magna (OECD 202, 1984)

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
284 mg/L

Additional information

One experimental study was performed according to the OECD 202 (GLP) with the water flea Daphnia magna. Nominal concentrations of 31.3, 62.5, 125, 250 and 500 mg/L were tested under static conditions. Test concentrations were verified by DOC-analysis at the beginning of the exposure period only. Stable test item concentrations during the test duration can be expected since the test substance is considered to be of low volatility based on the Henry’s Law constant of 0.208 Pa m³/mole. Immobilisation of D. magna was observed after 48 h resulting in an EC50 (48 h) of 284 mg/L based on nominal concentrations.
